I did so:
Font was larger, but the design has changed.

/* Я */
#bbpress-forums ul.bbp-lead-topic,
#bbpress-forums ul.bbp-topics,
#bbpress-forums ul.bbp-forums,
#bbpress-forums ul.bbp-search-results {
	font-size: 15px;
}
#bbpress-forums .bbp-forum-info .bbp-forum-content,
#bbpress-forums p.bbp-topic-meta,
#bbpress-forums .bbp-forums-list li,
div.bbp-template-notice p,
#bbpress-forums div.bbp-the-content-wrapper textarea.bbp-the-content {
font-size: 15px !important;
}
#subscription-toggle { 
background: #E7FFE8;
margin-left: 5px;
padding: 0px 3px 0px 1px;
border-radius: 2px;
font-size: 15px;
}
/* /Я */

The words “Voices” and “Replies” can be replaced with icons.
(bbp-forum-topic-count, bbp-forum-reply-count)
This saves space.
